Pushpa Tiwari, 40, a resident of Chinhat, was admitted to the hospital's emergency ward as a suspected case of celphos poisoning. She died last night during treatment, Hospital Director Dr Devendra Negi said.
The woman's body was kept in a deep freezer in the mortuary as an autopsy had to be conducted since it was a medico-legal case.
But this morning, her family members alleged that "parts of her face and neck were eaten up by a dog".
They also claimed that her ear rings and nose pin were missing.
A police team, which reached the spot, found paw marks of a dog near the channel gate of the mortuary.
An FIR has also been registered in connection with the matter, he said.
The services of the security supervisor and a guard have been terminated on charges of dereliction of duty, he said.
The Dr Ram Manohar Lohia Institute of Medical Sciences is a super-speciality hospital and one of the reputed and leading autonomous teaching institutes established by the Government of Uttar Pradesh.
